FOUNTAIN-PEN.

SPECIFICATION formingpart of Letters Patent No. 786,967, dated April 11, 1905. Application tied November 17,1904. serial No. 233,200.,

in fountain-pens, and particularly self-llingfountain-pens. Y

The main obj ect of the invention is to provide a pen of the class described with means for forcing the air from the ink-barrel to per-V mit atmospheric pressure to force the ink into said barrel on return of said 4meansto normal position.

The invention in its preferred form is illustrated in the accompanying drawings, where- 1n- Figure 1 is a longitudinal section of a pen constructed in accordance with my invention, the sack therein being shown in normal position. Fig. 2 is a similar view, the sack being distended to force the air from the ink-barrel. Fig. 3 is a sectional view of the ink-barrel. Fi is a Vsectional view of the connector. p g

Referring to the drawings, my improved pen comprises a barrel 1, arranged to contain ink and provided with the usual outlet 2 to receive the pen-feed 3. The opposite end of the barrel is reduced and threaded at 4 and partially closed by transverse plate 5, formed with a central opening 6, communicating with the interior of the barrel. The plate 5 is serrated or roughened on its face preferably by radial ridges, asl at 7, for a purpose hereinafter mentioned. The sack comprises a body 8 and a neck 9, together forming a tube-like structure, preferably closed at both ends. The body 8, hereinafter termed the sack, is constructedv of suitable material to permit its ready expansion under air-pressure and at its junction with the neck 9 is provided with a circumferentially-projecting flange or web 10. By preference the neck 9 is of slightly-heavier material than the sack 8, whereby the latter only will expand in the operation of the device.

11 represents the connector, comprising a cylindrical body prtion threaded at 12 to engage the threads 4 on the barrel and also formed with a channel 13, which when the parts are assembled is in alinement with the opening 6 in plate 5. The connector is reduced near its upper end, as at 14, to receive the shield 15, which is virtually a cap arranged to normally protect theneck 9 of the sack. The shield 15 is also shouldered and reduced at 16 to receive the usual pen-cap 17 when the pen is in use, it being understood that an additional pen-shoulder .18 is formed near the lower end of the barrel 1 to receive the pen-cap when desired.

In assembling the parts the sack is inserted through the opening 6 until the flange 10 of the sack rests against the corrugated portion4 7 of the plate 5. A washer 20 is then positioned to bear against the flange` l16, the washer beine moved to its position over the neck 9 of the sack. The connector 11 is then` positioned by screwing it upon the threads 4 of the barrel, after which the shield 15 is placed in position on the connector. To fill the pen, assuming the parts constructed as in the preferred form, the shield 15 is removed and the neck 9 clasped at its eXtreme end and compressed in any suitable manner, such as ,by rolling it upon itself until brought into contact with the upper end of the connector, the parts assuming the p0- sition shown in Fig. 2, except of course that the shield 415 and cap 17 are removed from the pen. This operation ofthe neck forces the air contained therein into the sack 8, and

the latter is distended to fill or partially fill the interior of the ink-barrel, as shown in ssi' 2, thus forcing the air ordinarily contained in the barrel through the outlet 2. The pen end of the barrel is then introduced into the body of the ink, and the coil of the neck 9, heretofore manually maintained, is

released, thus permitting the` parts' to re-A sume normal position and create a partial vacuum within the ink-barrel. Atmospheric pressure upon the body of the'inkv will force the sameinto the barrel, filling the pen.

It will be noted that the parts of my pen are few in number and of simple construction and that not a single joint can possibly .lOO

be reached by the ink, it being understood that the neck 9 of the sack completely iills the aperture 6 in the plate 5.` I prefer, of course, to construct the part of the usual hard rubber, With the exception of the sack and neck thereof, the former of which is of ordinary sheet-rubber material and the latter also of flexible rubber, but of sulicient strength to prevent distention during operation.

If desired, the neck and sack may be made separately and connected by a hard-rubber tube.

Having thus described the invention,What is claimed as new, and desired to be secured by Letters Patent, is Y l. A fountain-pen comprising an ink-ban rel, a sack held Within the barrel, and a neck connected with the sack and lexible to perzo mit compressing to distend the bulb.

2. A fountain-pen comprisingT an inkbarrel, a sack Within the barrel7 a neck connect ed with the sack and arranged to be conlpressed to distend the sack, and means for holding the combined sack and neck against longitudinal movement in the barrel.

3. A fountain-pen comprising an ink-barrel, a connector secured thereto, a shield removably joined to the connector, a sack Within the ink-barrel and a neck projecting from the sack and housed within the shield, said neck being llexible to permit compressing to distend the sack, and means to prevent longitudinal movement of the neck and sack. In testimony whereof I aiiix my signature in presence of two witnesses.
